My precious Gizmo came through the surgery like a champ. He is on some heavy narcotics for pain. This in turn is causing him to be constipated and not eat or drink very much at all. He has probiotics in a paste to help with the constipation. He hates it. It is a battle to et him to take most of the medications. Do any of you pet parents have any suggestions for giving medication and relieving the constipation?
